Next hope will move you 1/3 of the 4/9 missing, which is
, adding this to the path you have already moved is:

and you are missing 8/27 of the way.

, and adding this to the traveled path:

and you are missing 16/81 of the way.
The last and fifth hop is again one third of the missing path:
, and adding this to the already moved way:
